Engine Overview and Common Failures

The weight of the 13B-MSP engine according to the catalog is 112 kg. The engine number for the 13B-MSP is located to the left of the oil dipstick. First and foremost, this engine is known for its high fuel consumption, as well as oil consumption. Additionally, it requires high-quality lubrication, otherwise you can expect rapid wear of the apex seals. Typically, around 80-100 thousand kilometers, the eccentric shaft bearings often need to be replaced. The oil injectors require regular diagnostics and rarely last more than 50,000 km. Spark plugs should be replaced every 30,000 km, usually together with ignition coils.
